Smartnoble Microwave Anechoic Chamber， which is 5 m anechoic chamber. Because the distance between the antenna and the wall of the darkroom is larger than that of the 3M darkroom, it is easier to meet the requirements of Normalized Site attenuation. And the conversion correction relationship between 5m method and 10m method is better than that of 3M method. In addition, the test above 60MHz in 5m anechoic chamber can be defined as far-field test. In open-field test, there are many signals in the range of 60MHz to 100MHz propagating in the electromagnetic environment. Therefore, the performance of 5m anechoic chamber is superior to that of 3M open-field test.
Microwave anechoic chamber is a special room constructed by SA and metal shield. It provides man-made "free space" conditions. The test of antenna, radar and other wireless communication products and electronic products in darkroom can avoid clutter interference and improve the test accuracy and efficiency of the equipment under test. With the development of electronic technology, microwave anechoic chamber has been understood and applied by more and more people.
Microwave anechoic chamber is to use absorbing materials to create a closed space, which can create a pure electromagnetic environment in the anechoic chamber.
